Angular 未捕获错误：意外值''；由模块导入''；。请添加@NgModule注释

我正在尝试将我自己的自定义模块导入到应用程序模块中，但一直出现此错误

"Uncaught Error: Unexpected value 'ActionsService' imported by the module 'ReduxStoreModule'. Please add a @NgModule annotation."

它希望我添加一个@NgModule注释，但我的两个模块中都有@NgModule。我不知道我做错了什么。请帮忙

应用程序模块.ts

import { BrowserModule } from '@angular/platform-browser'
import { NgModule } from '@angular/core'
import { AppComponent } from './app.component'
import { ReduxStoreModule } from './Redux-Store/redux-store.module'

@NgModule( {
    declarations: [ AppComponent ],
    imports: [
        BrowserModule
        ,ReduxStoreModule
    ],
    providers: [],
    bootstrap: [ AppComponent ]
} )
export class AppModule { }

import { CommonModule } from '@angular/common'
import { NgReduxModule } from '@angular-redux/store'
import { NgModule } from '@angular/core'
import { ActionsService } from './actions'

const ImportsExports = [
    ActionsService
    ,NgReduxModule
]

@NgModule( {
    imports: ImportsExports
    ,exports: ImportsExports
} )
export class ReduxStoreModule { }

redux store.module.ts

import { BrowserModule } from '@angular/platform-browser'
import { NgModule } from '@angular/core'
import { AppComponent } from './app.component'
import { ReduxStoreModule } from './Redux-Store/redux-store.module'

@NgModule( {
    declarations: [ AppComponent ],
    imports: [
        BrowserModule
        ,ReduxStoreModule
    ],
    providers: [],
    bootstrap: [ AppComponent ]
} )
export class AppModule { }

import { CommonModule } from '@angular/common'
import { NgReduxModule } from '@angular-redux/store'
import { NgModule } from '@angular/core'
import { ActionsService } from './actions'

const ImportsExports = [
    ActionsService
    ,NgReduxModule
]

@NgModule( {
    imports: ImportsExports
    ,exports: ImportsExports
} )
export class ReduxStoreModule { }

服务应位于提供程序下而不是模块下，从模块中删除操作服务，并将其添加到提供程序下

const ImportsExports = [
  NgReduxModule
]
